There are a number of settings associated with SpamAssassin.

Filters

Filters allow you to automatically delete e-mail messages that are flagged by SpamAssassin. You will want to set the required "score" for SpamAssassin to begin marking messages as spam. The default is 5, but the higher you set the number, the more conservicate SpamAssassin will be.

Warning

Enabling this feature could cause you to lose email that is not spam, if a message meets or exceeds the defined score. Make sure SpamAssassin is configured properly for your account before using this feature.

 


If needed, you can disable the Auto-Delete tool, with the button immediately to the right of the Filters area.

Spam Box

Enabling the spam box will create an additional folder, named “spam,” where spam mail will be sent. This can be useful in preserving mail that may have mistakenly been filtered by SpamAssassin. It is recommended that you enable this feature.

...

  • Only the spam box may be accessed using the above address format; no other folders on your account are accessible in this way.
  • While this is not an issue for IMAP and webmail users, all users should periodically check and delete the contents of the spam box.
  • If you are unsure whether you use POP3 or IMAP to receive mail, you may be able to find this information on your email application's Preferences screen.

Configuration

When you click Configure SpamAssassin, you can add email addresses that should never be allowed to send you e-mail by typing the address into the blacklist_from box. A whitelist can be created in the same way at the bottom of the page. You can also specify scores that SpamAssassin should use for each particular instance.

Required Spam Score

SpamAssassin scans every message for spam indicators, then assigns it an overall score. You can modify the score required for SpamAssassin to flag a message as junk.

...

5.0 is the default setting, and is aggressive. It would be suitable for a single e-mail user, but overall you may want it to be higher [between 8 and 10].

Blacklisting

If you are receiving frequent spam e-mails from one particular domain name, and notice that SpamAssassin is not catching them by default, you can add that particular e-mail address to a Blacklist to force each message from that address to be flagged as spam.

...

By default there are 5 boxes for you to enter Blacklist entries. If you need more than 5 you will want to fill in all the boxes, click on Save, and then return to the Configuration page to see more available Blacklist boxes for you to utilize.

Individual Scores

You can generate your own tests for SpamAssassin to use when flagging mail messages as spam. Please see http://spamassassin.apache.org/tests.html to verify that you are not already covered by one of the hundreds of tests that SpamAssassin uses by default.

...

  • The first score is used when both Bayes and network tests are disabled.
  • The second score is used when Bayes is disabled, but network tests are enabled.
  • The third score is used when Bayes is enabled and network tests are disabled.
  • The fourth score is used when Bayes is enabled and network tests are enabled.

Whitelisting

If you notice that certain messages from an e-mail address are being flagged as junk by SpamAssassin when they should not be, you can Whitelist them.
